OILER FOR BEARINGS.

Application filed November 4, 1924. Serial No. 747,817.

To @ZZ 'whom t may concern Be it known that we. HnnsoHnL A. BENE- mo'rand Eni/Ann M. Molema, citizens of the United States, residingat Ea stOrange and South Orange, respectively, in the county of Essex and Stateof New Jersey, have invented certain new and useful Improvements inGilers for Bearings; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention relates generally to Oilers for the bearings of shafts andaxles and is especially designed for oiling the bearings, shafts andaxles of electric car wheel motors.

To these ends our invention consists briefly of a bearing provided withan upper funnel shaped box to contain the waste and oil and leading byan oil duct downward through the bearing to the bearing surface of thesame and of the shaft or axle, substantially as hereafter described andclaimed.

In order that our invention may be fully understood we shall firstdescribe in detail the mode in which we at present prefer to carry ourinvention into practice and then particularly point out the novelfeatures of the invention in the claims.

Reference is to be had to the accompany ing drawings forming part ofthis application in which like parts are designated by the saine numbersin all the figures.

Figure 1 is a perspective view showing our improved oiler applied to anarmature shaft bearing for an electric car wheel motor.

Figure 2 is an enlarged end, partly sectional view of the same.

Figure 3 is a sectional side elevation of the same.

Figure 4C is an end elevation showing our improved oiler applied to an(half) axle bearing for a car wheel.

Figure 5 is a sectional side elevation of the same.

Figure 6 is a plan view of the said axle bearing.

In the drawings, 1 designates the sectional housing for the motor andaxle of an electric car wheel motor, formed with a sleeve 23 to receiveand hold the bearing 9 of the armature and pinion shaft f1, and withaligned sleeves 2 to receive the bearings of the wheel axle 3.

As shown in. Figures l, 2 and 3, we prefer to form the armature shaftbearing 9 with a circular head portion 6 having peripheral fianges 5 tofit closely within a correspondingly formed chamber in the housing andits sleeve 23, and a concentric inner hub portion 'l' t0 project throughand outside the housing sleeve 23, the shaft bearing 9 extendingcontinuously through the head and hulo portions 5 and 7 respectively,which are strengthened by approximately radial ribs 8.

Rising from the hub portion 7 of the bearing outside the housing sleeve23, I prefer to form a funnel shaped waste box 10, lead- .ing downwardthrough an oil duct 12, to the bearing surface of the shaft 4l, so thatby filling the funnel shaped box 10 and the duct 12 with waste 11 andoil, the oil will be fed by gravity effeetually and continuously to thebearing surface of the shaft l.

l/Ve prefer to lit a removable cover 13 over the open top of the wastebox l0, for filling, replacing and enclosing the waste and oil therein.

In Figures l., 5 and 6, we have shown our improved oiler applied to thewheel axle bearing 22, the oil duct 18 being carried through the axlebearing 22 and the bearing sleeve 2, and the funnel shaped waste and oilbox 19, being` formed with a lower tubular extension which is forced 0rotherwise held in the oil duct 18.

We claim as our invention.

1. A removable shaft or axle bearing comprising a head portion, a hubportion pro jectng axially therefrom, a bore common to said head and hubparts, a funnel shaped waste and oil box rising from the hub portion andan oil duct descending from the waste and oil box into the bore of thebearing.

2. A removable shaft or axle bearing corn-V prising a peripherallyflanged head portion, a hub portion extending` axially therefrom, a borecommon to said head audhub parts, a funnel shaped waste and oil boxrising from the hub portion and an oil duct descending from the wasteand oil box into the bore of the bearing.

In testimony whereof we affix our signatures.
